POSTAL: Brain Damaged is considered the fourth branch in the series of video games about the adventures of the Dude. The setting is noticeably different from other parts of the franchise. The action takes place not on the streets of Paradise, but within the walls of a psychiatric hospital. The anti-hero ended up there after receiving a serious head injury. But it turned out that the hospital was conducting experiments on patients and even orderlies. People turn into bloodthirsty monsters. And the protagonist is trying to get out. His adventure blurs the line between reality and nightmarish fiction. Despite the fact that this is a spin-off, the franchise's signature dark humor has not gone away. As well as the opportunity to relieve minor need on passers-by. Only now it is a type of weapon.

POSTAL: Brain Damaged is a retro shooter with a first-person view. Instead of an open world, there are separate levels. The character began to move much faster and learned to make tackles. The gameplay has become more dynamic and meaty. It's similar to the latest iterations of Doom. The local arsenal includes a pistol with homing cartridges, a shotgun with a grappling hook mounted on it, a machine gun, a rocket launcher that fires holy projectiles, an energy cannon and other guns. And for close combat there is a shovel crossed with a circular saw. It can be used to deflect enemy bullets. Enemies are represented by various mutants, robots, clowns and other creatures. Fights with them take place in surreal locations. Killing opponents is accompanied by copious amounts of dismemberment and blood.
